Process for the production of an impregnated wood piece, impregnated wood piece obtainable by such a process and pencil having a sheath made of such an impregnated wood piece

A process for the production of impregnated wood pieces for use in pencil production, and pencils with shafts including such impregnated wood pieces, wherein the process comprises two process stages, namely a) a first process stage, comprising a first impregnation step, in which an untreated wood piece is at least partially, impregnated with a first aqueous impregnating solution of an impregnating agent selected from the group consisting of 1,3-dimethylol-4,5-dihydroxyethylene urea or a derivative or modification thereof, and a catalyst, and a subsequent curing step, in which the impregnated wood piece is cured in a hot steam atmosphere at an elevated temperature above 100? C., and b) a second process stage comprising a second impregnation step, whereby the impregnated, cured wood piece is at least partially impregnated with a second aqueous impregnating solution of a wax emulsion paraffin based as an impregnating agent.

METHOD FOR LACQUERING PENCILS, AND LACQUERING APPARATUS
20180326779 · 2018-11-15 ·

In a method for lacquering pencils by the push-through method, a respective pencil is guided through a lacquering chamber in order to apply a lacquer coat. After exiting the lacquering chamber, successive pencils butt against one another and are held against one another at their end sides such at a plurality of pencils form a stable strand which is guided, subsequent to the lacquering chamber, through a drying section, with the result that a respective pencil is held in a hovering manner on leaving the lacquering chamber. It is hereby in particular also made possible to use UV-curing lacquers, with the overall result that a very short total lacquering time for lacquering pencils, in particular cosmetic pencils, is achieved.
